Description
Ring 70 mm O.D. with boss, steel, galvanised is a laboratory support ring for secure positioning of glassware on retort stands. Fabricated from galvanised steel, it incorporates an 8 mm diameter connection, a three-point contact surface and a nickel-plated brass screw for reliable clamping. The 70 mm outer diameter accommodates common round-bottom flasks, beakers and other vessels used in heating, reaction and distillation setups. This ring from manufacturer Usbeck attaches quickly to standard retort rods, allowing height adjustment and stable three-point support that minimises tipping risk. The galvanised finish provides corrosion resistance under typical laboratory conditions, while the nickel-plated brass screw ensures smooth, durable fastening. Suitable for chemistry teaching labs, synthesis workstations and general laboratory scaffolding, the ring delivers dependable mechanical support without complex assembly. Its compact design and robust construction make it a practical everyday accessory for holding glassware during thermal or chemical procedures.

Questions about Ring 70 mm outside Ø with Bosshead
What is this article?
Ring 70 mm outside Ø with Bosshead is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Stand & rack accessories, inside Stands, clamps & racks, in Labware.
These are the extra rods, connectors, feet and labels that extend a stand or a rack. A right-angle connector is how a second rod leaves the first. The diameter has to match the rod already on the bench.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
